I bought a wheel that was thought to be for a 944 not knowing 944 wheels don't work on a 911. They sent it to me and I pulled the horn pad off and it was a 911.xxx.xxx.xx number. I lucked out and got a brand new NOS Carrera wheel for next to nothing. Part number should be under the horn pad.
If the hub will unbolt from the wheel you may be able to buy just the hub to make it work with the 911 for 135.00

Sorry didn't pay attention to what wheel you had in the pictures. Don't think it will allow a different hub.
